The amount produced by one tree times by how many trees:
(2.6 x 10^2) x (3.9 x 10^11)
260 x 390000000000 = 101400000000000 pounds of oxygen each year
101400000000000 / 365 = 280000000000 each day (rounded up)

ANSWER = 2.8 x 10^11

Sidana [21]

The value of the expression when g = -2 is -1

<h3>How to simplify the expression</h3>

Given the expression;

(5+2g)exp5

(5+2g)^5

For g = -2

Let's substitute the value of g in the expression

= ( 5 + 2 ( -2) ) ^5

Expand the bracket

= ( 5 - 4) ^ 5

Find the difference

= (-1) ^5

= -1

Thus, the value of the expression when g = -2 is -1
